Answer:
Original Number = let we assume it is x
Number after decremented = y = 60
Total decrease = z = x-y = x-60
% of decrease = ((x-60)/x)*100 = 7.3
(x-60)*100 = 7.3x
100x -6000 = 7.3x
100x-7.3x = 6000
92.7x = 6000
x = 6000/92.7 = 64.73
Original Number = 64.73

Answer: D .
Step-by-step explanation:
Given : Jenny studied the characteristics of two species of bacteria. The number of bacteria of species A, A(t), after t hours is represented by the function,
The number of bacteria of species B, B(t), after t hours is represented by the function,
Then, the difference in the number of bacteria, N(t), of both the species after t hours will be :-
Hence, the correct answer should be : D .
Answer:
56 meters.
Step-by-step explanation:
Please find the attachment.
Let the leaning tower's be h meters tall, when it was originally built.
We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.
Since we know that cosine relates the adjacent and hypotenuse of a right triangle.
Upon substituting our given values we will get,
Therefore, the leaning tower was approximately 56 meters, when it was originally built.
